Patented Dec. 24, 1912. 674,689. Divided and this application filed June 28 1912. Serial No. 706,440.

' Be it known that I, THOMAS J. ELLISON, a

citizen of the United States, residing at Terrill, in thecounty of Madison and State of Kentucky, have invented certain new and useful Improvements in Land-Markers, of which the following is a specification. I

i v This invention relates to improvements 1n land markers for corn planters, the present application being a division of my pending application, Serial No. 674,689, filed February 1, 1912.

It is the obj ect'of the invention to provide a device of the character described embodying certain novel features of construction to be hereinafter described and claimed.

In order that the inventionmay be better understood, reference is had to the accompanying drawings, in which Figure 1 is a side elevation. of themachine; Fig. 2 is a plan view thereof; Fig. 3

is a cross-section on the line 3-3 of Fig. 2;

. Fig. 4 is an elevation of one. of the'clutch members; Fig. 5 isa section on the line 5-5 of Fig. 2; and Fig.6 is a plan view of the furrow opener and the covering device carried thereby.

Referring specifically to the drawings, the

main frame of the machine comprisesside bars connected at the front and rear by cross-bars 11 and '12, respectively. To the front cross-bar is attached a draft tongue 13, and the side bars carry a transverse axle. 14 on which the wheels 15 on lWhlCh the machine travels are mounted, said axlebeing located substantially midway between the front and rear ends of the main framein order that the latter may be properly bal- I anced." The rearcross-bar carries a seat 16 for the driver, a scraper 17. for the wheels 15, and aside marker 18. One of the wheels 15 will be made fast on the axle .14 in any suit:

' able manner so as to operate as the drive On the axle 14 looselyinounted a sleeve wheel of the mechanism to be presently de-. scribed. L

19, which is adapted to be lockedtosaid axle by an adjustable clutch connection comprising the following parts :The sleeve 19 is formed midway between its ends with two laterally spaced disks 20 which are 'connected at their rims as indicated at 21. In

the space between the disks 20, the axle 14 carries a disk22,.which is keyed or otherwise made fast to the axle," the sleeve 19 hav v ing slots 23 so that the key for securing said I disk 22 may be applied. Each disk 20 has notches 24 in its periphery, which are uniformly spaced apart, and the disk 22 has notches 25, which are spaced apart irregu, larly. The sleeve islocked to the axle by means of a transverselatch-bar26, which is adapted to be placedin the notches of the disks. The latch-bar has a handle 27 and is connected tothe sleeve by. coiled springs 28, I which serve to hold it in looking position. Upon 7 lifting the latch-bar out w of the notches, the axle and the sleeve are'disconnected. I

The sleeve 19 has brackets 29 in which are mounted radially extending arms 30 arranged in pairs, the members of the respective pairs being spaced laterally and carrying'transverse shafts 31', on which are mounted, so as to turn freely thereon, rollers. 32 which serve as markers. The arms-30 are forced outward by springs 33, so that I the marker rollers yieldingly engage the ground, and also pass over obstructions ground. Three marker rollers are shown,

and theyare spaced equidistant apart. In operation, should the markers not register with the markstmade by the, same on the previous bout, the operator disengages the latch bar 26, 'after which the markers .may"

be set into proper position. x

The seed boxes 34 aresecured by brackets.

35 to the side-bars 10, and they are provided eachwith the usual seed plates (not shown) which have N a bevel gear 36in mesh with which is'a bevel gear 37 adjustably fastened to the sleeve 19 by a set'screw 38. Each side of the machine carries a seed box as herein described together; with a dropping mechanlsm, so that two rows are plant'ed simultaneously. It will be notedthatthe seed boxes are located abovethe axle, in view of I which they may be driven from the sleeve' 19, and the dimensions of-the entire machine are .reducedto. a minimum. The machine is also rendered morecompact, and complicated, driving gears are dispensed .with. Each seed box carries: afseedgchute 39 -con-" taining a valve '40,; which is pivoted intermediate its ends ne bolt 41' mounted in a slot 42 in the side walls of the chute so that the valve may be adjusted. Aspring 43 connected to the valve serves to open the same. The valve is closed by a cam 44 mounted on the sleeve 19, into the path of which cam the upper. end of the valve extends. IVhen the machine is in operation, the valve is periodically opened to drop the seed. The valve is opened by the spring 43 when that end of the valve which engages the cam slips off the same, and the valve is closed when the cam again engages the same. The lower end of the seed chute extends into a furrow-opener 45 which is carried by a lever arm or drag bar 46 connected by a knuckle 47 to an arm 48 extending at an angle to the lever arm. Both furrowopeners are supported in this manner. The knuckles 47 are pivoted to the front ends of the side bars 10, said bars being downwardly inclined at their front ends, so as to tenninate below the plane of the axle 14. The arms 46 are inclined rearward and downward to the furrow-openers to which they are bolted or otherwise secured. The arms 48 are inclined upward and rearward and extend outside the marker arms 30, and the rear ends of said arms 48 are connected by across bar 49 carrying a latch 50 which is engageable with a rack-bar 51 pivoted to the rear cross bar 12, said latch and rack bar serving to lock the supporting arms of the furrow-openers and thus hold the latter in adjusted position. By locating the pivotof the supporting arms of the furrow-openers as shown, the latter will not come in contact with the seed-chutes when they are raised out of operative position, there being ample room between the front of the chutes and the corresponding ends of the furrow-openers to enable the latter to be swung upward without interference by the seed-chutes. It will also be noted-that the furrow-openers are set close to the perpendicular center of the wheels 15, they being located slightly in advance thereof, so that the ground may be as loose on one side as on the other to pull through.

Each furrow-opener carries a drag for covering and packing, said drag comprising two laterally spaced plates 52 which are bowed outward at their rear ends, and connected at their forward ends. The drag is located between the side walls of the furrowopener and its bowed ends project from the rear end thereof. The front end of the drag is pivoted at the corresponding portion of the furrow-opener, as indicated at 58, and has a cross bar 54 in which is adjustably mounted a screw stem 55 secured by a nut 56. To one end of the screw stem is connected a spring 57 which is anchored to the furrow-opener, and which spring serves to force the drag downward andyieldingly press it into the ground. The tension of the spring is adjusted by operating the screw stem in an obvious manner.

One of the arms 48 carries a lock for holding the marker arms 30 stationary when the machine is not in operation. The lock comprises a rock shaft 58 supported at one of its ends in a bracket 59 carried by the arm 48, and having its other end passing through an aperture 60 in the cross-bar 49 and formed with a return bent end 61 which is adapted to enter a second aperture 62 in said crossbar, whereby the shaft is locked. The shaft has a lateral arm 63 the extremity of which is forked as indicated at 64. The fork is so located that when the shaft is rocked toward the center of the machine, said fork swings inward and may be slipped over one of the marker arms. Before the shaft can be rocked it will be necessary to pull it-in the direction of its length to disengage the end 61 from the aperture 62. The shaft is operated by a spring 65 coiled around it and connected at one end thereto, the other end of the spring being fastened to the arm 48.

The front cross bar 11 carries a clevis 66 to which the draft tongue 13 is connected so that it may be raised or lowered.

I claim:

1. In a planter, a wheel-driven axle, a frame supported on the axle, a rotary marking device mounted on the axle, said device having radial arms, driving means for the marking device, a clutch for the driving means, and a lock carried by the frame and adapted to engage the aforesaid arms when the driving means are disconnected.

2. In a planter, a wheel-driven axle, a sleeve loosely mounted on the axle, laterally spaced disks fast on the sleeve, said disks having a notched periphery, a disk fast on the axle between the aforesaid disks, said second-mentioned disk having notches in its periphery which are irregularly spaced apart, a latch bar adapted to span the disks and seat in the notches thereof when brought into registering position, and a marking device carried by the sleeve.

3. In a planter, a wheel-driven. axle, a frame supported on the axle, a rotary -marking device mounted on the axle, said device having radial arms, a rock-shaftcarried by' the frame and having a lateral arm the outer end of which has a fork to straddle the aforesaid arms, and means for operating the rock-shaft to engage and disengage the fork.

In testimony whereof I ailix my signature in presence of two witnesses.
